Digital Responder extended from the main circuit and the circuit. Priority encoder circuit, latch, decoder circuit will be the team' s output on the display input signal with the control circuit and the host switch to start the alarm circuit, the above two parts of the main circuit. Timing circuit and decoding circuit through second pulse signal to the monitor output to achieve the timing function, constitute the expansion of the circuit. After wiring, welding, testing and other work forming digital Responder.
